New research suggests that individuals who stop using blockbuster weight-loss injections like Wegovy and Mounjaro tend to recover lost weight at a significantly accelerated pace than those who stop conventional diet and exercise regimens.
Research printed in a major health publication points out that while obese individuals can lose a large proportion of their body weight while undergoing treatment, the mass is regained at an average rate of nearly a kilo each month after stopping.
"Individuals using these treatments must be informed of the danger of rapid weight regain when the therapy is stopped," stated researcher Dr. Susan Jebb.
Such speed of regain means a return to starting weight in about a year and a half.
Analyzing Approaches
The study, which looked at dozens of trials involving over 9,000 of participants, contrasted the results of the injectable medications with older methods.
The team note that people who shed pounds through lifestyle changes alone generally have a slower weight regain—perhaps 100 grams monthly—after stopping.
Understanding the Fast Regain
Experts propose the way of the jabs accounts for the accelerated weight return.
GLP-1 drugs mimic a natural hormone called GLP-1, which helps regulate hunger.
"Artificially providing the hormone concentrations far above than normal may cause the body to generate a reduced amount of its endogenous hormone, and could diminish responsiveness to its actions," said Dr. Adam Collins, a dietetics specialist.
"Discontinuation of this hormone supplement leads to appetite is no longer kept in check, making binge eating much more probable."
A Chronic Condition?
Health authorities recommend the jabs for individuals with weight-linked health risks, accompanied by prescribed diet and exercise modifications.
A number of clinicians argue that, due to the likelihood of weight regain, the treatment might need to be long-term.
This view is reinforced by drug manufacturers, who note that the findings "emphasize the persistent character of obesity," akin to managing diseases like hypertension.
Patient Testimonies
People who have stopped the medication report a intense resurgence of hunger.
"It was like something flipping and you're instantly starving," recalled an individual.
This difficulty is exacerbated if patients have not established sustainable lifestyle or habit changes during therapy.
Growing Adoption
Figures indicate that millions of people in the UK have tried weight-loss jabs in the past year, with desire continuing to grow.
- Use is more common among women than males.
- The middle-aged age group shows the greatest level of interest.
- A large proportion access the medications through private healthcare rather than public health services.
Ultimately, clinicians stress that while the jabs are potent tools for weight loss, they are not a magic cure and lasting health benefits hinges on combined behavioural management.
